Car will not start after engine is hot .Will not even turn over.
After driving a good bit of distance if you shut the engine off & try to start it again the engine will do nothing. The lights, radio, etc. work fine but there is no clicking noise or anything from the engine bay. I have a new battery, battery cables, & alternator. Took it to the shop & the mechanic said that it was a bad wire going to the alternator. THAT WASN`T IT!!!!! I was left stranded again. Someone please help!!!!!!!!!

Re: Car will not start after engine is hot .Will not even...
Hi,in many cases the starters dont work when they get hot because they are getting bad when it does not start ,try to start it by turning the key on and with a screw driver touch both cables at the starter to check if it start,

If the car is running hot, it probably has a sensor that shuts the car down. It is designed to keep you from damaging your engine if It gets too hot. It will not let you crank it until the car has cooled off sufficiently. Find out what's causing the car to overheat. If it's not overheating, you may just have a bad temperature sensor. It will probably be on the radiator. Please do not remove this sensor if your vehicle is overheating. Your car will only drive a short distance before catastrophic damage occurs, and you'll be out a few thousand dollars to replace it.
Does it get hot mainly when parked or stopped at a red light or does it get hot even when the car is in motion?If its only when your stopped,the cooling fans are probably not working due to a blown fuse,relay or bad fan motor.If the coolant inside the reservoir seems to boil once the engine gets hot,that can be caused by a defective radiator cap.A blown head gasket will also cause overheating.If you let the engine idle for a few minutes,shut it off,pull all of the spark plugs,see if any plug or two adjacent plugs are wet with coolant, that's a sign of a blown head gasket.If you constantly need to refill the radiator with coolant, that's another sign.
I would have your alternator checked. It sounds like you have a grounded heat sik in the alternator. This will drain the battery down to no voltage, even a new batt. Try getting a jump start to start the car, if it will stay running when you disconnect the cable, then disconnect the negative battery terminal. The car will stay running if the alternator is working properly!!!! Hope this helps, plese post solved on fixya.com.So I get credit for a solved problem if it does. If not, check back and give me more info. P.S. Your check engine light will be on for about 50 miles or so. Do not worry about this it will reset after you drive this distance. Start the car and shut off several times. It is also good to let the car sit overnight so that the sensors will come online after a cold start.
Sounds very much like your fuel pump is done for. After it runs for a bit it starts to get hot & quiets working once it cooled down it started working again. This is very common but more frequent if fuel in tank is low. It realy will take a fuel system test to verify.
try burping the cooling system a few times or could be your thermostat. as far as the belt squeek, you can take a litle bit on silicone grease and put it on the belt in one spot with the car off. let it run for a little bit and the squeek should stop
This sounds like a "heat soak"issue(something is failing on a hot engine shutoff).The low tech solution I used to use often was a can of brake cleaner.Get the car hot,shut it off,and try to restart.If it wont,try spraying a quick burst of cleaner at various sensors(to cool them off) and trying to start it again.The most common sensor I would find as the cause was the crankshaft position sensor.(Sometimes a little tough to get at).
check for a bad fuel pump relay. it maybe geting hot and shutting down. it may be a bad coolant tempurature sensor also, that sends info to ecm.The engine will think it was still cold, even though it was not, causing all kinds of things to run draggy. thats why it runs ok when its cold. it sends wrong info to computer. thinking its cold, when in reality its warm. have a good day !!
Seems to me it's the engine coolant temperature sensor or the connecting wire to it. Some Model/Year (MY) hyundai's have TWO (2) temperature sensors.. one for the instrument panel/gauge, the other strictly used by the ECU (Engine Control Unit)... if this sensor goes bad, it sends the wrong data/signal to the ECU and this can affect engine performance.
